Wait for the reduction of the estimated limit of statistical deviations of
measurement results of surface beta-particles flux density to a value not exceeding
3 %. After that, enter five measurement results in the report with a 5-second
interval.
Calculate the average value of surface beta-particles flux density and main
relative error of measurement in accordance with the recommendations of DSTU
GOST 8.207:2008 standard.
The radiometer is acknowledged to have passed the verification if the relative
main error in percentage when measuring surface beta-particles flux density does
not exceed 20+150/F, where F is a dimensionless value that is numerically equal to
the value of measured beta-particles flux density in part./(cm
